EXTENSIBLE RACK.

Application nled January 18, 1922. Serial No. 530,019.

j of which the following is a specification.

This invention `relates to improvements in extensible racks, and more particularly tosuch devices adapted for use in connecftion with cabinets such as driers or the like. One object thereof is to provide a device of the type described which shall be so constructed as to afford a high degree of economy in floor space.

Another object of the invention is to provide a device 'of the character described in which the means for supporting the carrying frames when drawn out of the cabinet extend therefrom only at such times when a frame is in extended position, and is capable of being Withdrawn when the frame is withdrawn.

A further obj ect is to provide in a cabinet of the type described,means for suspending the carrying frames when the latter are drawn out of the cabinet, which means shall be capable of being drawn into the cabinet when the racks are returned thereinto, and which shall be eiicient in operation to a high degree. j y

A still further object is to provide a drier in which the drier frames may be suspended when drawn out of the cabinet bymeans movable in and out of the cabinet with said frames.

Other objects of this invention will in part be obvious and in part hereinafter pointed out. j

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinater described and of which the scope of application will be indicated in the following claims.

In the accompanying drawings, in which is shown one of various possible illustrative embodiments of this invention,

Fig.- 6 is a detailed cross-sectional vie taken alongfline 6--6 of Fig. 2.

Referring in detail to the drawing, the embodiment of the invention there' illlis- 'l trated shows the invention as applied-tela drier comprisin a dryinof inet 10 provide with a heater-'11 for supchamberor'cabplying heat thereto. A plurality of drying frames 12 are adapted tobe reciprocated in and vout of the cabinet and supported in position in the manner hereinafter more fully described. Each off these drying frames comprises a front vertical.pvanel 13 adapted to provide a closure or and a rear vertical panel 14. Extending between said panels 13 and 14' are racks-f' 15 froml which the clothes or other objects to .be dried .may be suspended. At the bottom of the drier frame isa horizontal'screen 16 for the drippings from the materials or objects being dried.

Suitably secured to the top .of the drier frame is a T-rail 17 for reciprocating the drier frame and sustaining the same in extended position. This T-rail 17 travels in a preferably U-shaped channel kor guide rail to one of the vertical faces 21'of said T-rail by means such as the screws 26, and is further secured to the rear panel 14 of the drier frame by means such as the screws 27 and an attaching plate 28. At about the mid-length of the guide rail 18, or any other suitable position, is secured a stop piece 29 having a projecting ear 30 on the side thereof nearest t0 the lug member A cam piece 30 is secured to the guide member 22 and has cut-away cam faces 30a, 30", and a horizontal face 30C. rll`he cam follower 31 is secured at therear end of the Trail 17 and has a cut-away face 31a adapted to ride on the cam faces 30a, 30" and a flat or horizontal bottom face 31c adapted to ride on the face 30C of the cam piece. Extending from the side 18a of the rail 18`is a pin 18b disposed in the completely closed position of the drier rack behind the cam piece 30. This cam follower 31 is secured to the T-rail by means of screws 32 operating in elongated slots 33 soY that the member 31 may have limited upward and downward motion.

The guide rail 18 is provided at the rear end thereof with a roller rail 34 which rides along the top wall of the C-shaped member 21 as the guide rail moves in and out of the casing. If desired, another T-rail 35 may be secured to the drier frame at the bottom thereof and a guide rail 36 provided therefor with rollers'37 so as to help reciprocate the drier racks in and out of the easing with a minimum of friction and wobbling.

When the drying racks are all in closed position, the front panels 13 completely close the front of the cabinet, and for the purpose of admitting air thereinto when the drier frames are all in closed position, a screen 38 is provided for the bottom of the cabinet.

The operation of the mechanism for reciprocating the drier frames and supporting them in extended position outside of the cabinet will now be described. As a drier frame is drawn out of the cabinet, by means for example of the handle 39, theI T-rail 17 rides on the rollers 19 in the guide rail 18, lthe bottom l"'rai1 35 at the same time riding in the fixed guide rail 36 on the rollers 37.

When an outward pull is had on the drier frame the T-rail 17 'will cause the rollers 19 to turn and as the latter run on the base 21 of the fixed guide member, the rails 17 and 18 will move outwardly but the former will move an appreciably greater distance than the latter until the projection 25 engages the lug 30 when both bars will move together. The plate 31 is so shaped at its forward end that it will ride over the lug 18b as the rail 17 moves outwardly, but on the return movement of the rail 17 the inner end of the plate 31 will engage the lug 18b and compel the rail 18 to move inwardly to its extreme position. As this extreme posirinasce tion is reached the cam plate 30 is engaged by the plate 31 and causes the latter to be elevated out of engagement with the lug 18b to allow the rail 17 to move to its extreme inward position.

It will thus be seen that the initial movement of the rack will cause both bars`17 and 18 to move outwardly on the roller mounting, but the movement of the bar 18 is relatively slow until the bars are coupled by reason of the engagement of the projection 25 with the lug 30.

In Fig. 2, the full lines show the drier frame and the guide rail 18 in one position after the projection 25 has struck the luFf 29, and the dotted lines show the panel or the drier frame and the guide rail after the drier frame has been fully drawn out of the cabinet. During the forward motion of the T-rail, when the member 31 reaches the cam 30, it rides up on the face 30a and then along the face 30c so as to clear the pin 18h. lt then rides down on the face 30b with the screws 32 in the highest positions of the slots 33 as in Fig. 2. Upon the return of the drier frame into the cabinet, it will be clear that at first the drier frame moves by itself independently of the guide rail 18 until the member 31 strikes the pin 18b when the guide rail 18 is carried along back into the cabinet. i

It will be clear from the foregoing description that when the drier frames are not in use and are all in closed position. no supporting structure extends either along the floor, or from the ceiling or cabinet. `When a supporting structure for the drier frame becomes necessary upon withdrawal of the drier frame from the cabinet, it is supplied by the movable suspension and guide rail 18 which extends from the cabinet only for such time as the drier rack is in extended position. rlhis supporting structure is a part of the drier itself, requires no mechanisms or devices outside of the cabinet extending either on the ceiling or floor of the room and is readily returned into the cabinet so as to take up no space when the drier frames are closed. Also it will be noted that the lIT-rail 17 and the guide rail 18 both L operate within a substantially completely enclosed casing formed by the members 21., 22 and 23, thus preventing the dropping of dirt or rust down into the cabinet on the materials being dried.

`While the invention has been described with particular reference to its application to driers,` it will be readily understood that the same dominant features of construction might be embodied in other cabinet constructions such as tiling cabinets and the like. rlhus, where the invention is applied to filing cabinets, as will be readily under stood, suitable carrier frames or telescopic holders may be employed in connection with llO ice

all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. An extensible rack of the character described, comprising a stationary guide bar, a U-bar, rollers on the U-bar mounted to run on the guidebar, a rack, a T-bar constituting a part of the rack and mounted to run on the rollers, and means coupling the rack bar and the U-bar after the former is moved a predetermined distance.

2. An extensible rack of the character described, comprising a stationary guide bar, a U-bar, rollers on the `U-bar mounted to run on the guide bar, a rack, a T-bar constituting a part of the rack and mounted to run on the rollers, devices coupling the rack bar and the U-bar and compelling their uniform movement after one has been moved a predetermined distance relative to the other, and means for uncoupling the bars as they are moved inwardly.

3. An extensible rack of the character described, comprising a stationary guide bar, a U-bar, rollers on the U-bar mounted to run on the guide bar, a rack, a T-bar constituting a part of the rack and mounted to run on the rollers, a lug on the U-bar, a cam plate on the rack bar adapted to ride over the lug when moved in the one direction, and to couple with the lug when moved in the other direction, and a fixed cam engaged by the cam plate to release the latter from engagement with the lug on the inward movement of the rack bar.
